Introduction

The SEPN 3020S is an automatic coupling/decoupling network (CDN) designed for EFT/burst, surge, and ring wave immunity testing in accordance with IEC 61000-4-4, IEC 61000-4-5, and IEC 61000-4-12. It couples the specified disturbances onto the power lines of EUTs rated up to 300 V AC, 20 A single phase or 300 V DC, 20 A. The CDN is compatible with 3CTEST CCS, EFT, CWS, and RWS series generators.

Features

> Supports EUT power supplies up to 300 V AC (line-to-line) or 300 V DC

> EUT current capacity 0 ~ 20 A

> EFT/burst coupling voltage up to 5.5 kV

> Surge coupling voltage up to 8.0 kV

> Ring wave coupling voltage up to 8.0 kV

> Automatic selection of coupling paths and phase synchronization

> LED indication of the active pulse coupling path
